Python In Practice - 15 Projects to Master Python - callable( )

The video tutorial explains how to determine if a function instance is callable. It begins by introducing the concept of callable functions and proceeds to demonstrate the creation of a simple function. The tutorial then tests the function's callability using the print function, highlighting that parentheses are not needed to check if a function is callable. The video concludes by confirming the function's callability through a program run.
